SPECIFICATION forming part of Letters Patent No. 722,297, dated March 10, 1903.

Application filed November 17,1902. $erial No. 131,668. (No model.)

To all whom it may concern:

Be it known that I, ISADORE GOTTFIELD, a citizen of the United States of America, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and usefullmprovements in Machines for Polishing Stovepipes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to machines for polishing Stovepipe; and its obj ectis to provide a machine for the purpose which is adapted to receive lengths of pipe of any size orlength and firmly hold and revolve the same, at the same time applying the liquid polish evenly to the pipe in such a manner that it will not be wasted or thrown about.

The invention also consists in providing means whereby the pipe is quickly and easily placed in the machine and taken therefrom and in providing a suitable receptacle for the liquid polish and a dauber for applying the same, which dauber is so arranged that the liquid is constantly stirred thereby; and it further consists in making the parts adj ust: able and in providing certain other new and useful features.

To this end the invention consists in providing a suitable frame upon which is mounted a driven shaft provided with a conical head to engage one end of a length of pipe and an opposing longitudinally-movable shaft having a similar head to engage the opposite end of the pipe. Between the adjacent ends of these shafts is provided a receptacle for the liquid blacking, and suspended within said receptacle or trough is a dauber pivoted to the frame to turn up against the pipe to apply the blacking thereto and at the same time agitate the liquid in the trough.

The invention also consists in making the parts interchangeable and adjustable, and in the particular arrangement,construction,and combination of parts, all as hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which-- Figure 1 is a side elevation of a device embodying my invention with the supportingframe partially broken away; Fig. 2, a plan view of the same with the upper portion sectioned on the line 2 2 of Fig. 1; Fig. 3, asection on the line 3 3 of Fig. 1; Fig. 4, a section on the line 4 4 of Fig. 1 looking toward the right, and Fig. 5 a section on the same line looking toward the left.

As shown in the drawings, A is a supporting-frame,for1ned of iron pipe,to which frame is secured the bed or table B, formed with a central longitudinal semicircular trough O and at each end upwardly-projecting standards D and D, having bearings D at their upper ends for the shafts E and E, respectively. Fixed on the shaft E between the bearings D and held against longitudinal movement thereby is a drive-pulley F, and each end of said shaft, which projects some distance beyond the bearings, is screwthreaded, the outer end toreceive a collar G, against which the circular polishingbrush G abuts when screwed on the shaft, and the inner end, which is reduced to form a shoulder, is screw-threaded to receive the conical head I-I, secured thereon by a collar H at one side engaging the shoulder on the shaft and a nut H at the other side. The shaft E extends some distance outside its bearings D ,in which it is longitudinally moviable, and on the inner end of said shaft is a conical head H, similar to the head H and held thereon by a collar 1, secured to the shaft at one side, and a nut I on the end of the shaft, which is set up against a shoulder l on the shaft, said collar I forming a handhold to move the shaftlongitudiually. Sleeved on the shaft E between the bearings D is a sleeve J, provided with a setscrew J, which is set up against the shaft to hold the same from moving longitudinally.

In each standard, directly beneath the innor bearing thereof, is formed a vertical bearing-slot K to receive a bearing-sleeve K, said sleeve being formed with a flange K at one end to engage the outer face of the bearingslot and at its opposite end is screw-threaded to receive a nut K to engage the inner face of the same and secure the sleeve at any desired height in the bearing-slot. The trough C is semicircular, with its edges extended a short distance above the face of the table B, and a board L, provided with trunnions L to project into the bearing-sleeves K, hangs downward into the trough and is provided with a facing of wool or other material L to form a dauber L, which is turned up to contact the stovepipe by a bar M, provided with a bandle at one end and attached at its opposite end to an arm M on one of the trunnions L Secured to the tableB at the corners of the trough are the castings or corner-irons N and N, the irons N being formed with slots to re ceive the ends of the spatter-boards O, which extend along the sides of the trough, and the irons N' with slots to receive the opposite ends of said boards and also the ends of a board extending across at the end of the trough to form a support P for the pipe, said board being concave at its upper edge to fit the convexity of the pipe.

The inclined faces H of the heads H and H are formed with corrugations, so that when the pipe is engaged with the head H at one end and placed on the support P at the otherend and the shaft E moved longitudinally to en gage its head H with that end of the pipe the pipe will not slip thereon, but will be firmly held between the heads H H and rotated.

When pipes of smaller or larger diameter are to be polished, heads of the proper diameter are substituted for those on the machine, or these heads may be made with a longer tapering face to fit any size of pipe, and any of the ordinary lengths of pipe may be polished, as the shaft E is of such a length that the head H may be moved the length of the trough.

To cause the dauber to contact the pipe at the proper angle and place to do good work, it is adjusted up and down in its bearings by loosening the nuts K and adjusting the bearing-sleeves up or down in their bearing-slots, and when the facing L becomes worn in one place the dauber may be adjusted to change the point of contact. The trough being semicircular and the dauber moving in an arc within the trough keeps the liquid thoroughly agitated.

The rotary brush is used in polishing pipeelbows; but if the pipe is rusty a buffer may be substituted for the brush, and it is obvious that any convenient power may be used to rotate the shaft H.

Having thus fully described my invention, what I claim is- 1. In a stovepipe-polishing machine, the combination of a conical head, means for rotating said head, and an opposing conical head adapted to be moved toward and from the rotated head to clamp a length of pipe between said heads.

2. In a Stovepipe-polishing machine, the combination with two opposing heads one of which is movable toward and from the other to clamp a length of pipe; of a trough, and a dauber adapted to project into the trough and to be turned to contact the pipe.

3.
